To ZZ whom, "6 may Gourmet:

lle itknowu that LNV-ILLIAM l?. ZELL, a citizen of the United States,residing at Denver, in the county of Arapahoe and State of Colorado,have invented certain new and useful Improvements in Hydranis, of whichthe folis a specification. y,

This invention relates to certain new and useful improvements inhydrants, having for its object to inexpensive means whereby freezing ofthe delivery-pipes and also to prevent the accumulation of waste wateraround the said pipes and valve-casing; and with this object in view theinventionconsists in the novel construe-tion, combination, andarrangement of the Darts hereinafter more particularly described.

l tional viewof line 2 2 of Fig. l.

In the accompanying drawings, forming a part of this specication, and inwhich like letters and numerals of reference designate correspondingparts, Figure l is a vertical sec a hydrantembodying theinven tion. Fig2 is 'an enlarged detail sectional view of the lower part of the hydranton the Fig. 3is a'detail elevation of one section of the inclosingcasing of the valve-chamber.-

Referring more particularly to the drawings, A designates the body of ithe hydrant, which extends above the surface of the ground, as usualgandis provided with a discharge-nozzie l, communicating with thedelivery-pipe 2, extending through the body A and below the surface ofthe ground. At the lower end the delivery-pipe communicates with avalvecasing B, which may be of vany suitable shape or construction, andwiththe lower end ofl this casing communica-tes asuppiy-pipe Extendingbelow the valve-casingfl a cylindrical casing Li, of suitabledimensions, having an open lower endand provided at its upper end with aperforated drip-plate 5, which plate constitutes a seat for the valve;casing. The casing or waste-water chamber iis greater in diameter thanthevalve-casing,

and the perforations'in the plate 5 are formed outside the edges of thesaid valve-casing, so

aste be free from all obstruction. It will be obvious that thedrip-plate 5 and casing 4 may bc formed in a single piece; but prefergprovide simple,4 eiiicient, and to prevent theor to the flange 6 serialNl. 676,572. [No man.)

ably the plate 'is ilormed separate from thecasing and is supported uponan annular shoulder 6 at the upper end of the said casing, as shown, theshoulder being surrounded by a vertically-extending fiange 6?. It ispreferred also to form the casing i at its nlower end with auoutwardlyprojectiug,iiange '.7, thereby providing an extensive bearingfor the end of the casing and rendering; it less liable to settle.

lower end to thc'surlace of the ground is a frost-jacket 8,whiclrjacketis of greater diameter than the said pipe to leave a spacearound the same. At its lower end the jacket 8 is formed with one ormore perforationsf?, Athrough which an'v imi-,er of'cnndensatinn .or

l upon the drip-plate and waste-water .chamber 4. Inclosing thevalve-casing' B and likewise the' lower end of the frost-jacket 8 is acasing 9, preferably formed in two semicon'ical sections, which arebolted or otherwise secured together, and is formed a vertical collar,which rests upon the drip-plate 5 at the outer edgethereof and closelyconforms to the inner face/of the flan ge 6, thereby forminga closejoint, which will prevent earth from entering the interior of thecasing. The casing is likewise formed at its upper edge with a collar6', which closely hugs the exterior surface of the frostjacket and formsa broad continuous bearing therefor. f As above stated; it is .preferredto form the casing 9 in two sections, and while these may in certaininstances be either bolted together' itis usually smilie-lent to fromthence into the form one casing with a lip or flange 6c, which projectsfrom the inner face thereof and is adapted thereby forming lap-jointsbetween the sec-i tiene from e. interior ofthe said casing. By thusforming the casing it will be obvious thatposi! tiveV securing devicesbetween the sections are not necessary, as the pressure of the earthupon the exterior to overlapthe edge o ffthe abutting section, i

. Y 95 the casing and serving to excludedirt Surrounding thedelivery-pipe 2 from its moisture which collects in the jacket may flowat the lower edges of the casing vertical edge of each section of thefoo thereof will tend to force` the collars into close contact with theexterior I for the reason which willl adapted to which isa valve 10,

of the frost-jacketand the nteriorsurface of the flange 6*. Thiscasing9issucientlylarge to leave a space around the valve-casing and inaddition to protecting the valve-casing from frost it serves to preventsand or dirt from entering and obstructing the perforations of thedrip-plate.

Ihile the valve-casing at the lower end of the delivery-pipe may bedispensed with and the valve be located within the lhydrant-body, it ispreferred to arrange the valve as shown, presently appear. FormecLin thevalve-casing is a valve-seat, supported upon the lower end of avalve-rod 12, which extends centrallyv through the delivery-pipe 2 andis surrounded at its upper end bya coilspring 13, interposed between astationary guide 14: and a collar 15 upon the rod, the said spring 13servingl normally to hold the valve firmly to its seat. As a convenientmeans of operating the valve a lever 16 is provided, which. lever ispivoted at one end within the hydrant-body and has its. rearendprojecting through a slot in the said body, and intermediate its endsthe lever bears upon the upper end of the valve-rod 12 in such mannerthat when it is depressed the valve -10 will be forced from its seatagainstl the stress of the spring 13.

Obviouslyif water be left within the delivery-pipe between thevalve-easingand the discharge-nozzle there is liability of its becomingfrozen. In order that this may be guarded against, the delivery-pi pe isprovided immediately above the valve-casing with a drip-opening 17'-,through which water in the pipe may fiow out upon the d rip-plate 5 and'thence into the waste-water chamber l. This drip-opeuing is always openwhen the valve 10 is closed; but as it. is undesirable that water shouldescape through it when water is being withdrawn through thedischargenozzle 1 a slide-valve 1S is provided, coinprisinga cylindricalShell the outer periphery of which i'nalies close contact with theinner' i wall ofthe delivery-pipe. This shell is conncctefl by means ofradial arms `2O with a collar 2l upon the valve-rod, the said collarbeing fixed to the rod to move therewith. Normally the lower edge of theshell is im mediately above the opening 1T, leaving said openingunobstructed'. When, however, the valve-red isdepressed to open thevalve 1U, the

.shell isalso lowered, thereby closing the said opening, lYhen the valveis again closed, the

openingis uncovered, allowing the water remaining in the delivery-pipeabove the valvexeasing to flow to the waste-water chamber.

It wilhbf course be obvious that the opening l and valvel-S may bedispensed with, if desired; but it is preferred to employ them,

iliefreczing-of the delivery-pp`is precluded thereby.

Various changes in thc,construetion and arrangementxepnrts maybe madewithout departing from the spirit or scope of the invention, and Itherefore do not wish to be limited .to the precise construction andarrangement shown, since What I claim isii.
